Claims
- 1. A method of treating a substantially cholesterol-free egg white product to improve its refrigerated shelf life which comprises heating said egg white product to a temperature of from approximately 150.degree. F. to approximately 162.degree. F., said heating occurring while said egg white product is transported through a heat exchanger at a velocity sufficient to create turbulent flow of said egg white product, holding said egg white product for from 45 to 60 seconds at said temperature and immediately thereafter cooling said egg white product to a temperature of from 25.degree.-40.degree. F. in as short a period of time as is possible, whereby the growth of micro-organisms that survive the thermal treatment is discouraged so as to obtain the maximum shelf life of the finished product.
- 2. The method of claim 1 wherein said egg white product is preheated to a temperature of from 120.degree. F.-140.degree. F. and then homogenized prior to being heated to a temperature of 162.degree. F.
- 3. The method of claim 1 wherein said egg white product comprises liquid egg white, starch, and oil.
- 4. The method of claim 3 wherein said liquid egg white is present from 70% to 99%.
- 5. The method of claim 3 wherein said starch is present in said egg white product in an amount up to 2%.
- 6. The method of claim 3 wherein said oil is present in said egg white product in an amount up to 5%.

- 8. The method of claim 7 wherein said egg white product additionally contains flavoring, coloring agents, and vitamins.
- 9. The method of claim 1 wherein said cooled egg white product is immediately aseptically packaged and frozen for a period of one to two weeks.
- 10. The method of claim 9 wherein said egg white product comprises liquid egg white, starch, and oil.
- 11. The method of claim 10 wherein said liquid egg white is present from 70% to 99%.
- 12. The method of claim 10 wherein said starch is present in said egg white product in an amount up to 2%.
- 13. The method of claim 10 wherein said oil is present in said egg white product in an amount up to 5%.
- 14. The method of claim 9 wherein said egg white product has a pH of approximately 7.0 to 7.4.
- 15. The method of claim 14 wherein said egg white product additionally contains flavoring, coloring agents, and vitamins.
- 16. A substantially cholesterol-free egg white product with an extended refrigerated shelf life prepared by treating an egg white product by heating said egg white product to a temperature of from approximately 150.degree. F. to approximately 162.degree. F., said heating occurring while said egg white product is transported through a heat exchanger at a velocity sufficient to create turbulent flow of said egg white product, holding said egg white product for from 45 to 60 seconds at said temperature and immediately thereafter cooling said egg white product to a temperature of from 25.degree. F.-40.degree. F. in as short a period of time as is possible, whereby the growth of micro-organisms that survive the thermal treatment is discouraged so as to obtain the maximum shelf life of the finished product.
- 17. The product of claim 16 wherein said egg white product is preheated to a temperature of from 120.degree. F.-140.degree. F. and homogenized prior to being heated to a temperature of 162.degree. F.
- 18. The product of claim 16 wherein said egg white product comprises liquid egg white, starch and oil.
- 19. The product of claim 18 wherein said liquid egg white is present in said egg white product from 70% to 99%.
- 20. The product of claim 18 wherein said starch is present in said egg white product in an amount up to 2%.
- 21. The product of claim 18 wherein said oil is present in said egg white product in an amount up to 5%.
- 22. The product of claim 19 wherein said egg white product has a pH of approximately 7.0 to 7.4.
- 23. The product of claim 22 wherein said egg white product additionally contains flavoring, coloring agents, and vitamins.
- 24. The product of claim 16 wherein said cooled egg white product has been immediately asceptically packaged and frozen for a period of one to two weeks.
- 25. The product of claim 24 wherein said egg white product comprises liquid egg white, starch, and oil.
- 26. The product of claim 25 wherein said liquid egg white is present from 70% to 99%.
- 27. The product of claim 25 wherein said starch is present in an amount up to 2%.
- 28. The product of claim 25 wherein said oil is present in an amount up to 5%.
- 29. The product of claim 24 wherein said egg white product has a pH of approximately 7.0 to 7.4.
- 30. The product of claim 29 wherein said egg white product additionally contains flavoring, coloring agents, and vitamins.
